请注意：

左双引号（）=＆放大器; ldquo

left double quotation (") = &ldquo

右双引号（）=＆放大器; rdquo

right double quotation (") = &rdquo

左单引号（'）=安培; lsquo的

left single quotation (') = &lsquo

我目前的正则表达式是这样

My current regex is this

(?<!.*&ldquo.*)&lsquo

，匹配和放大器; lsquo的在这里（这是正确的）：

It matches the &lsquo in here (which is right):

&ldquoThis is a sample&rdquo &lsquosample text

这也匹配和放大器; lsquo的在这里（我不希望发生的，因为单引号是左，右双引号内）：

It also matches the &lsquo in here (which I don't want to happen because the single quote is inside the left and right double quote):

&ldquoThis &lsquois a sample&rdquo

我怎么能写一个正则表达式匹配每一个和放大器; lsquo的是不是左，右报价在

How can I write a regex that will match every &lsquo that are NOT inside the left and right quotation

感谢您的帮助！

如果我理解UR question..This可能是你想要的。

If I understood ur question..This may be what you want

(?<!&ldquo.*?)&lsquo(?!&rdquo)
